TS7016: Could not find a declaration file for module class-transform.

[eldoccc]

I was looking forward to use this updated version of class-tranformer but got cut short when i got this error :

@rollup/plugin-typescript TS7016: Could not find a declaration file for module 'class-transform'. '/home/.../node_modules/class-transform/lib/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/class-transform` if it exists or add a new declaration (.d.ts) file containing `declare module 'class-transform';`

8 import { plainToInstance } from "class-transform";

I tried clearing my node_modules and reloading my IDE.
Am I missing something ?
